I hadn't heard of drywells. The permaculturists would use swales to a similar effect - capture surface water until it has time to soak in, and provide organic matter to soak it up like a sponge. In some instances it looks remarkably effective. This sounds like the more industrial scale approach, but I'm sure there are tradeoffs.
